My blade

I sit at the window,
staring up at the moon.
it looks the shade of crimson; a color i so often saw...
the color of blood.
o how i crave
the feeling of a blade,
the cool steel on my bare skin.
you've mad me so mad,
but now i am glad,
for again i have a reason
to cut myself again.
you left me once,
you left me twice.
now your with her...i bet it is nice.
but you'll now regret
what you've done.
you've put me through all this pain,
i take my silver blade,
and make a deep cut down,
you've caused me all this pain,
and now i will end it all.
i take the blade and cut even deeper,
i watch as the blood drips onto the floor.

(this isnt finnished yet)

if anyone has any suggestions on how i could change this to make it better, please,I'm open to them.

thank you very much :)
